DE FOREST CURTIS WILLIAMS, OF PITTSBURGH, AND WILLIAM MARSH UPDEGRAVE, OF JOHNSTOWN, PENNSYLVANIA.

COIN-CONTROLLED SCALE.

Application filed June 16, 1913.

To all whom it may concern Be it known that we, Dn Fonnsr CURTIS V. nouns and \VILLIAM M. Urnnonixvn, citizens of the United States, Dr. Fonns'r CURTIS VILLIAMS residing at Pittsburgh, in the county of iillcgheny and State of Pennsylvania, and WILLIAM M. Urononavn residing at Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Coin- Controlled Scales, of which the following is a specification.

This invention relates to improvements in coin controlled scales and has for its object to provide a weighing machine so constructed as to make its operation very simple while assuring absolutely correct work.

Another object of the invention is to provide mechanical means for shifting a poise on a scale beam whereby the poise and its shifting mechanism will become automatically detached from one another.

Another object of the invention is to provide a scale with a vertically movable shuttor for the beam of said scale.

Another object of the invention is to provide means for operating a poise shifter and means for disconnecting said shifter with said first means.

tional view of a shaft and lever shown in rotated position.

It will be noted by comparing Figs. 1 and 3 that we illustrate our device to show its operation with either a one or two beam scale but most commonly it would be used with the two beam scale, however, in order not to complicate the drawings, in all of the views with the exception of Figs. 1 and 10, a one beam scale is illustrated. The poise operating mechanism in either a one or two beam scale would be the same.

Like reference characters indicate like parts throughout the specification and in the various views in the drawings.

1 indicates our improved coin controlled scale having a platform stand 2, a casing 3, and an upper case 4-. Mounted on the stand 2 is a platform 5 which is provided at its forward end with an electrical contact point 6 held normally above the contact 7 by means of the spring 8. When a weight is placed upon the platform 2 the spring 8 is overcome and the member 6 engages the member 7 closing an electrical circuit thereby providing current for the lamp 9 within the case 4 whereby light is provided in order that the figures on the scale beams 10 and 11 may readily be seen by a person standing on the platform 5. All of the electrical connections, the spring 8 and lamp 9 above described are shown in dotted lines in Fig. 2.

The face 12 of the case 4 is provided with an opening 13 in which the glass 1 1 is mounted in order that the scale beams may be exposed to View. A coin receiving slot 15 is provided in said face 12 which is connected to the chute 16, which is adapted to direct a coin. through the slot 17 in the bottom wall 18 in the case 4, into the receptacle 19 on one end of the balance arm 20 which is fulcrumed and pivotally mounted on the pin 21 secured to the bearing 22 fixed to the under side of said wall 18. A guide member 23 is provided to guide the receptacle 19 to the slot 17. On the opposing end of the arm 20 is a weight 2 1 which is adjustable on said arm by means of the screw 25, whereby said arm 20 may be nicely balanced in order that it may be operated with a coin of any desired weight. A pin 26 is provided on said arm 20 which is slidable in the slot 27 in the link 28, the upper end of which is pivotally connected to the lower end 29 of the trip 30 which is pivotally mounted in the slot 31 in said wall 18, the free end of said trip being provided with a hook 32 normally held raised by the spring 32. Said hook 32 is adapted to engage the end 33 of the crank lever 34 which is pivoted at 35 on the free end 36 of the radially pivoted adjusting member 37, the end 38 of which is provided with an arcuate slot 39 through which projects the thumb screw 10. By loosening this screw the member 37 may be rotated in either direction on the pin 41 in order that the fulcrum 35 of said crank lever 34 may be nicely adjusted to a proper position. A spring 42 has one end connected to the arm 43 of said crank and another end connected to the screw 4 1 fixed in said wall 18 so that when a coin passing through the slot 15 falls into the receptacle 19, it will overbalance the arm 20 causing it to take the position shown in dotted lines 20 in Fig. 3, in which case the pin 26 will engage the edge 15 of said slot 27 forcing the link 28 and the end 29 of the trip 30 to move up into said slot 31 and free the hook 32 from the said arm 4-3, thus permitting the spring as to draw said arm toward said screw 1 1 causing the end 17 of the arm 48 of said crank 34: to engage the lever 49, shifting its position so that the dog 50 thereon will disengage from the recesss 51 in the plunger rod 52, thus permitting the spring 53 fixed to the pin 51 on the inner end of said rod and to the eye 55 secured to the inner surface of the face 12 to thrust the forward end 52 of said plunger outwardly through an opening 56 (shown in dotted lines in Fig. 5), said lever 49 being held in the normal position by means of the spring 62, whereby said dog 5O is held into one of the recesses 51. Mounted pivotally in the case a is a vertical rod 57 upon which is fixed a series of levers 58, 59, 60 and 61. The lowermost of these levers, which is lever 58, has its free end seated over the plunger rod 52, whereby the roller 63 will engage one edge of lever 58 so that when the plunger rod 52 is pushed inwardly by manual engagement with the plunger head 64-, said roller will actuate said lever 58 and cause it to rotate said rod 57. To the lower surface of the lever 59 is pivoted one end of a link 65 in the other end of which is provided an elongated slot 66 through which the pin 67 on the arm 43 passes, whereby said link 65 is loosely connected to said arm 13 and has a free move ment on said arm.

Pivotally mounted to the bearings 6869 the latter shown dotted in Fig. 9) are vertically radially movable hangers 70-71, the lower ends of which are pivoted to the vertically movable shutter 72, said hangers 70 and 71 being flat and held in position by the straps 73 and 7 1 between which and said shutter said hangers are movable. Connected to the pin 75 on said shutter is a loose joint member 7 6 to which is pivoted one end of the link 77, the other end of which is pivoted to the lever 61 fixed to said shaft 57. l Vhen the plunger 52 is pushed inwardly of said case the roller 63 operates the lever 58 which in turn rotates the vertical rod 57 causing the lever 61 to have a radial movement which draws the link ?7, which pulls the shutter 72 toward said rod 57 thereby causing the shutter to be drawn to a raised position as shown in dotted lines T8 in Fig. 9, thereby exposing the scale beam 10 to view.

Normally the shutter 72 is held in a raised position and is held in its raised position by the lever 61 drawing on the link 77. The lever 61 is held in its position shown in Fig. 15 whereby it draws upon said link 77 by the rotated position of the rod 57 which is held in said rotated position as before eX- plained when said plunger member 52 is pushed inwardly of said casing and held to its position by said dog 50.

When the coin falls into the receptacle 19 causing the arm 20 to over balance, thus disengaging the hook 32 from the arm -13, the spring as drawing on said arm causes the end d7 of the arm 18 to trip the lever t9 disengaging the dog 50 from the recess 51 and pe 'mitting the spring 53 to force said plunger member 52 outwardly whereby said roller 63 will disengage said lever 58 after which the weight of the shutter 7 2 will cause it to drop to lowermost position, thereby drawing, through the medium of the link 7'7, upon the lever 61 fixed to the shaft 57 which turns said shaft to its normal position, shown clearly in Figs. 3, 5 and 9.

Fixed to a clutch member 82 is one end of a shaft 81 the other end of which is mounted in the bearing 79. member 82 is provided with a bearing portion 83 which is mounted in the bearing 80. Projecting through the face 12 of the case 4 is a rotatable rod Set, the free end 85 of which is freely rotatable in the bearing 83. Mounted near the inner end of said rod S t is a clutch member 86 adapted to engage said clutch member 82. A screw 87 on the clutch member 86 projects into a kerr' 88 on said rod 8%, whereby said rod and memh r 86 are held in rotatable relation with one another. Mounted between the collar 89 on the rod 8st and the end 90 of the clutch member 86 is a coil spring 91 which is adapted to force the clutch member 86 into frictional engagement with the clutch mem ber 82 whereby the rotation of the rod 8% and the member 86 will cause the rotation of the clutch member 82 and the shaft 81. The rod 84 has a head 85 projecting outwardly of the face 12 for the rotation of the member 84:.

Fixedly mounted on the shaft 81 is a sprocket wheel 92 which operates the sprocket chain 93 which is supported at the The clutch opposing side of said case 4 by a sprocket wheel 94 mounted on the bearing 95. The opposing ends 96 and 97 of said sprocket chain are fixed to the upper end of the lever which is fixedly mounted upon the shaft 99 rotatable in the bearing 100 on the lower end of a sliding member 101 which is slidable upon the parallel horizontal bars 102 and 103, the ends of which are mounted in the links 104 and 105 seated in the sockets 106 and 107. The rods 102 103 are held in fixed parallel relation to one another by the links 108 and 109 which are adjustable on said rods and which also act as stops whereby the movement along said rods 102, and 103 of the member 101 may be regulated. Pivotally mounted in the upper end of the member 101 is a friction member 110 in which is fixed a rubber tip 111 the protruding end 112 of which is adapted to engage the upper surface of the rod 102. The spring 113 connected to the pin 114 and to the free end 115 of the member 110 forces the tip 111 into contact with said rod 102 whereby the member 101 will not too freely slide upon the rods 102 and 103.

To the end 116 of the shaft 99 is fixedly secured a bifurcated member 117, the arms 1.18 and 119 straddle the reduced portion 120 of the pin 121 fixed to the rear surface of the poise 122 mounted on the beam 10. The member 101 is provided with a pair of pins 173 and 174 adapted to control the radial. movements of the arms 118 and 119. Fixedly mounted on the upper surface of the end 116 of the shaft 99 is a leaf spring the opposing ends 124 and 125 of which abut the screws 126 and 127 that are threaded through the lugs 128 and 129 on the member 101. T he function of this spring 123 is to cause the shaft and the member 117 thereon to maintain a normal position whereby the arms 118 and 119 will normally be held out of contact with the pin 120. The purpose of the member 101 is to slide the poise to any desired position on the scale beam 10, but it is essential in a scale that will maintain any accuracy, that means must be provided whereby the poise operating member instantly become detached from any contact whatsoever, with the poise, otherwise it would be impossible to correctly balance the scale beam. The pin 121 is provided with a head 130 which is larger than the space between the arms 118 and 119 so that it would be impossible for any horizontal movement of the poise operating member 101 to disconnect the member 117 from said pin 120.

Vertically mounted adjacent the rod 57 is a rotatable rod 131 to the lower end of which is fixed a crank lever 132 which is operated by the roller 133 on the pin 54 mounted on the end of the plunger member 52. \Vhen said plunger member is driven in the roller operating on the arm 134 causes the shaft 131 to rotate, thus rotating the lever 135 fixedly mounted on the upper end of the shaft 131. This lever 135 is provided with a bifurcated end 136 which straddles the reduced portion 137 of the clutch member 80, so that when said shaft 131 is rotated the arms 136 and 136 of said bifurcated lever horizontally moves the clutch member 86 on the rod 84 against the tension of the spring 91 and out of contact with the clutch member whereby the head 85 may be freely rotated without in any way acting upon the operation of the machine.

The lever 60 on the shaft 57 is connected to a link 138 connected to the dog 139 which is pivotedto the hanger 140 depending from the top 141 of the case 4. Vertically slidable in the hanger 142 is a bolt 143 having a slot 144 in which is pivoted a trip member 143 having an inclined upper surface 14.6 which is engaged by the horizontally disposed head 147 of the dog 139. The member has a portion 148 which in its normal position rests within slot 144 but which is adapted to be projected from said slot by the operation of the dog139. The cam surface 149 of said dog abuts against the rear surface 150 of said trip member, forcing said portion 148 outwardly against the tension of the spring 151, said spring being adapted to push said portion 148 back into the slot when the dog 139 assumes a normal position. The bolt 143 is provided with an enlarged head between which and the lower surface 153 of thesocket member 154 is seated a coil spring 155 adapted to normally hold said head projected above the surface of said top 141.

Mounted on the top 141 is a bracket 156 having a chamber 157 to which is fixed one end of a coil spring 158, the other end of said spring being fixed to the member 159 on the rear of the frame 160 in which is seated a bent mirror 161. On the peripheral frame 162 is a groove 163 in which are four recesses 164 at equal distance around said peripheral edge. into which. the bolt head 152 is adapted to seat. From the above description it will be seen that a rotary movement of the rod 57 will cause the dog 139 to press the member 145 and with it the bolt, 143 downwardly drawing the head 152 out of one of the recesses 164,permitting the rotation of the frame 160 to move onefourth of its circumference until the head 152 which immediately rises after the disengagement of the dog 139, to seat in the succeeding recess 164. whereby the mirror frame will be held against further movement until another operation of the machine. The spring 158 may be put under tension in order to rotate the mirror frame 160 by lowering the head 152 and revolving the frame. The mirror 160 being bent concave or convex as desired, in one position, will have the effect of broadening whatever it reflects, while in its neXt position will have the effect of lengthening that which it reflects.

Mounted in thewall of the case 1 or in any suitable position within said case or casing is a numberingmachine 165 having a lever 166 attached to the link 167 operated by the lever 61, whereby each operation of the shaft 57 will operate the numbering machine 165 and thus a record will be kept of the number of times the machine is operated and will thus total the amount of coins dropped into the slot, so that each time the coins are removed from the coin receptacle 168 it will be unnecessary to count them, the number being determined by the indicated number on the numbering machine.

On the end of the scale beam 10 is an. arm 169 having an upwardly bent portion 170 carrying an arrow head 171 the point of which is adapted to aline with the point of the arrow head 172 painted on the glass 11, said arm being bent so as to project under the shutter 72 whereby the sale arm may be balanced when. said shutter is lowered, shutting off the view of the scale arm when the point of the arrow 171 alines with the arrow point 172 the scales will be nicely balanced.

The operation of the machine is as fol-,

lows :After the machine has been operated it leaves the shutter 7 2 in a raised position, the plunger being shoved into the case l as far as possible, and the member 133 holding the crank lever 132 in such a position that the rod 131 is held rotated and the bifurcated lever 131i is holding the clutch member 86 out of engagement with the clutch member 82 whereby the knob 85 may be freely rotated without having any effect whatsoever on the operation of the machine. To operate the machine it is necessary to drop a coin into the slot 15 which drops into the receptacle 19 overbalancing the arm 20 which through the link 28 trips the latch 82 from engagement with the bell crank 23% whereby said crank will trip the dog d9 releasing the plunger 52, thus permitting the spring 53 to force said plunger outwardly, thereby freeing the crank lever 132 and per mitting the spring 91 to force the clutch member 86 into frictional engagement with the clutch member 82 whereby the sprocket shaft 81 may be operated by rotating the knob 85, thus permitting the movement of the poise operating member 101 on the bars 102 and 103, so that the scale with its weight may be balanced, this being accomplished while the shutter 7 2 is in its lowered position hiding the scale beam 10 from view. As soon as the beam is nicely balanced, which may be determined as previously explained,

the ierson being weighed then pushes in the plunger 52, the roller 63 thereon operating against the lever 58 operates the rod 57 causing the lever 61 to draw on the link 77 and raise the shutter 72 thus again exposing the scale beam and the poise whereby the weight may be ascertained. The pushingin of the plunger 52 causes the arm 59 through the link 65 to set the bell crank 31 releasing the lever 19 permitting it to engage with the recesses 51 in the plunger 52 thereby holding the plunger in an inward position and the member 138 holding the crank lever 13 1- in such position that the bifurcated lever 136 on the rod 131 holds the clutch member 86 out of engagement with the clutch member 82 whereby the machine is again in a set position to receive the next coin.

lVhile the poise operating device described in the above specification is essential in order that this weighing machine will properly and correctly weigh, still the same poise operating mechanism is adapted for use in combination with many other weighing machines.
